96 prostar w/lt1 alternator question

I need to know the original part number for the alternator in a 96 prostar with a LT-1. Mine went out and I'm not near the boat and I need to order a new one. Also I want to up the amps to compensate my stereo so can anyone recommend a place to order and model that will work the best?? Thanks!

I'd start with calling skidim.

I think this is the direct replacement from skidim:


I also have a '96 LT1 and thought my alt was going this summer. I searched on here and found two things I will share...

First... the ground wire on the back of the alternators corrode a lot. I went to see if my ground wire was corroded and I broke the ground wire off just trying to find it. I crimped a new end on the wire and presto... My alt was only running 10v to 11v at idle and would hit 12v to 13v when at speed.

Second... during my search on here, many recommended having the old alt rebuilt by a local shop. I check into it and found a local source that would rebuild it for a little under $100. When mine finally does go, I will rebuild. If you want the detials of new vs rebuild, search the site.

Your last question was about increased output. I have never seen a marine alt with increased output. You are lucky to find a direct repalcement, let alone a selection of outputs. Let us know what you find out on this one...

I am wondering if my alternator is not performing properly on my 95-lt1 also.

It only reads 12.5 - 12.8 volts on the PP gauge

Should it not be reading 13.8 - 14.2??

Now I do think that I am in need of a new battery, it took a substantial amount of charging to get the battery to hold a charge

But that shouldn't affect how much voltage the alternator is putting out should it?
I live in my own little world. But it's OK - They know me here

Yes, a weak battery could make for some crazy things happening.
